Description

car brake lever

technical field

The invention relates to a car component, in particular to a brake lever on a car.

Background technique

The car's parking brake lever is located to the right of the driver's seat. When performing the parking brake, the driver presses down on the brake pedal with his foot, and pulls out the parking brake lever with his right hand to make it rotate upward around the hinge point; when he wants to release the parking brake, step down and hold brake pedal, pull slightly on the parking brake lever, press the button on the end of the handle with your thumb, and lower the parking brake lever to its original position. As shown in Figure 2, a traditional car brake lever is composed of a rod body 1, a handle 2 and an unlock button 3, wherein the rod body 1 is a straight rod structure, and the mounting end of the rod body 1 is bent downward to form a mounting lug. There is a positioning hole 4 at the bending part of the end, and a cable installation hole 5 is opened at the end of the mounting lug. The operating end of the rod body 1 is fitted with a handle 2 , and an unlock button 3 is arranged at the end of the handle 2 . For ease of operation, the setting of the brake lever should ensure that the driver's right hand can hold the handle 2 when it hangs down naturally. In the above structure, since the rod body 1 is a straight rod, and the length L3 between the center of the positioning hole and the end of the handle 2 is about 135 mm, the starting angle of the brake rod swinging around the positioning hole 4 is relatively high, and the swing angle of the brake rod Yes, the end angle of the brake lever is relatively high. On the one hand, it does not conform to the principle of ergonomics. It takes a lot of force to pull the handle when parking; on the other hand, the driver cannot fully pull the handle when parking. If it is in place, it will cause unstable parking, and the vehicle may slide under its own weight after people leave, posing a safety hazard. In addition, the bottom surface of the handle 2 is flat, which is not conducive to grasping during operation, and the comfort is poor.

Contents of the invention

The technical problem to be solved by the present invention is to provide a car brake lever with labor-saving operation.

The technical scheme of the present invention is as follows: a car brake lever, including a lever body, a handle and an unlocking button, a handle is fitted at one end of the lever body, an unlocking button is set at the outer end of the handle, and the other end of the lever body is bent downwards, An installation lug is formed, a cable installation hole is opened at the end of the installation lug, and a positioning hole is opened at the bending part of the end of the rod body. The middle part of the rod body is bent and deformed downward, and the rod body is divided into two sections from the deformed part of the middle part, with an included angle of 153-163° between the first section and the second section; the outer end of the handle is connected to the first and second sections. The distance L1 between the outer corners where the two sections are connected is 80-86 mm, and the distance L2 between the center of the positioning hole and the outer corners where the first and second sections are connected is 70-76 mm.

In the present invention, the rod body is designed into two sections, the positioning hole on the second section is hinged to the mounting seat, and the cable installation hole is connected to the cable. When the driver's action acts on the handle, the first and second sections rotate around the positioning hole. . Since the distance L1 between the outer end of the handle and the outer corner of the connection between the first and second sections is 80-86mm, the distance L2 between the center of the positioning hole on the second section and the outer corner of the connection between the first and second sections It is 70-76mm, and the sum of L1 and L2 is greater than the distance from the end of the handle to the center of the positioning hole in the traditional structure. According to the principle of leverage, it saves more effort when operating the handle. At the same time, there is an included angle of 153-163° between the first section and the second section, so that the position of the handle on the first section is lower than that of the traditional structure, thereby reducing the starting and ending angles of the swing of the handle around the positioning hole. While meeting the needs of ergonomics, it makes the operation more convenient and labor-saving, and at the same time, it is conducive to the driver to fully pull it in place when parking, eliminating the safety hazards caused by unstable parking.

The preferred solution is that there is an included angle of 158° between the first section and the second section, the distance L1 between the outer end of the handle and the outer corner where the first and second sections are connected is 83 mm, and the center of the positioning hole The distance L2 to the outer corner where the first and second sections connect is 73mm.

The bottom surface of the handle is composed of two planes and a concave arc surface along its length direction, the two planes are smoothly transitioned by the concave arc surface, and there is an included angle of 170-175° between the two planes. The above structure has a beautiful shape, and the four fingers of the hand act on the concave arc surface to exert force during operation, which is conducive to grasping and has good comfort.

Beneficial effects: the present invention is ingenious in design, simple in structure, beautiful in appearance, and labor-saving in operation. While facilitating parking operations, it can ensure that the driver is fully pulled in place when parking, and eliminates potential safety hazards caused by unstable parking.
